Computer Science at St Andrews

The entry requirements say AAA, but I'm having trouble believing that is actually the standard grades there since it does so well in the rankings. My predictions are currently AAA (trying to get them up to A*AA), do you think I would have a real chance applying there?

It's great that you're aiming high! St. Andrews is indeed a top-ranking university, and while the entry requirements are listed as AAA, it's important to remember that these are just the minimum grades. Universities often consider applicants holistically, taking into account other factors like personal statements, references, and extracurricular activities.
Your current predictions of AAA are definitely competitive, and aiming for A*AA could further strengthen your application. Plus, your dedication to improving your grades shows your commitment and drive, which universities value.
Keep up the hard work, and don't forget to highlight your passion for computer science and any relevant projects or experiences in your application. You've got this!

You'd have a chance, yes, but don't rule out the (high) chance of rejection. I've seen people with better predicted grades be rejected from similar unis.
